How quickly do Dragonflies get their adult colour?
British Dragonfly SocietyWhen dragonflies and damselflies first emerge from their water-borne larval stage, most have very muted colours. Depending on weather conditions, it can take a few days for them to gain their bright adult colour. Common Blue damselflies are often a pale pinkish-brown rather than sky-blue on first emergence. Some damselflies, Blue-tailed are a good example, undergo a gradual colour change as they age.
Why are they called Dragonflies?
British Dragonfly SocietyPossibly the earliest reference to the name is from Francis Bacon's "Sylva Sylvarum: or a Naturall Historie in Ten Centuries." (a curious hotch-potch of experiments, observations, speculations, ancient teachings, and analytical discussions on topics ranging from the causes of hiccups to explanations for the shortage of rain in Egypt).
What do Dragonflies eat?
British Dragonfly SocietyMainly, adult dragonflies eat other flying insects, particularly midges and mosquitoes. They also will take butterflies, moths and smaller dragonflies. There is one Asian species which takes spiders from their webs! The larvae, which live in water, eat almost anything living that is smaller than themselves. The larger dragonfly larvae are known to catch and eat small fish or fry. Usually they eat bloodworms or other aquatic insect larvae.
What enemies do Dragonflies have?
British Dragonfly SocietyDragonflies do have enemies. Among the species that catch and eat adult dragonflies and damselflies are birds (e.g. Wagtails and Hobbies), Spiders (many damselflies are caught in webs), Frogs, and larger species of dragonflies (which catch and eat other dragonflies and damselflies). In the larval stage, which is spent underwater, they are preyed on by fish, frogs, toads and newts, other water invertebrates - and Kingfishers (see photo below).
What is the difference between Dragonflies and Damselflies?
British Dragonfly SocietyDragonflies and damselflies belong to the insect order known as Odonata, meaning "toothed jaw" - their mouthparts are serrated. They are often referred to collectively as "dragonflies", however there are two different sub-orders. Damselflies are insect in the sub-order Zygoptera (meaning "yoke-winged"). All four wings are near enough equal in size and shape. They are usually small, weakly flying insects that stay close to the water margins or water surface.
Do Dragonflies Bite or Sting?
British Dragonfly SocietyNo, although large dragonflies if held in the hand will sometimes try to bite, but fail to break the skin. They have a lot of "folk names" which imply that they do (such as Horse stinger), but they don't use their egg-laying tube (ovipositor) for stinging. They also don't bite (people) but they are a fearsome predator of other flying insects.
Are there any legends and myths about Dragonflies?
British Dragonfly SocietyThere are many legends and myths about dragonflies and damselflies from all parts of the world. Many are evident from their common nicknames. In the UK, Dragonflies were called 'Horse-Stingers'. This name may come from the way a captured dragonfly curls its abdomen as if in an attempt to sting. Another possible explanation of this name is that the big Aeshnids etc. are/were often seen flying round horses in fields. Here they were actually feeding on the flies attracted to the horses.
Do Dragonflies have antennae (feelers)?
British Dragonfly SocietyYes, Dragonflies do have a pair of antennae. They are very tiny and difficult to see. If you look at the photo on the right you will just be able to see the antennae between the front of the eye and the front of the face of this Emperor dragonfly. As dragonflies rely much more on their eyesight than on a sense of touch or smell, they do not need the large antennae found on some beetles and moths.
How much? How quickly?
Frequently Asked Questions About the Colonix and Toxinout Pr...Many of our customers have reported weight loss (anywhere from a few pounds to 20 or more) as a result of the Colonix program. One thing that almost everyone boasts about is a flatter belly. Keep in mind that the average person could be lugging around 10 – 20 pounds of impacted fecal matter in his or her intestines. As the Colonix program sweeps the colon clean and this waste finally leaves the body, such a person is bound to lose weight.
Why do Dragonflies sometimes appear in large swarms?
British Dragonfly SocietySeveral species of dragonfly are known to collect in large aggregations or swarms. In Europe, the Migrant Hawker (Aeshna mixta) and the Four-spotted Chaser (Libellula quadrimaculata) have been observed to do this. In most cases this appears to be due to very favourable feeding conditions in the locality. It may also be a "courting" group with males actively searching for females. This is less likely as males are much more aggressive to each other when looking for a mate.

Can work be done quickly for a bear belonging to a child (adult?) who can't be parted for too long?
Oldenbears Frequently Asked QuestionsYes of course, provided the necessary materials are in stock. It often happens that a beloved teddy has to be taken from a child for necessary repairs and we always try to keep the time they are parted to the 'bearest' minimum.
How long do Dragonflies live? Is it true that they only live for one day?
British Dragonfly Societythe shortest, a dragonfly's life-cycle from egg to death of adult is about 6 months. Some of the larger dragonflies take 6 or 7 years! Most of this time is spent in the larval form, beneath the water surface, catching other invertebrates. The small damselflies live for a couple of weeks as free-flying adults. The larger dragonflies can live for 4 months in their flying stage. In Britain, lucky Damsels seldom go more than two weeks and Dragons more than two months.
Can I use Dragonflies to control mosquitos or other flying pests?
British Dragonfly SocietyDragonflies certainly do eat large numbers of flying pest species, but using them to control these pests is not really feasible. There have been a number of studies carried out and only in very restricted and tightly controlled environments have Dragonflies, or their larvae, been shown to be able to control pest numbers. In the open, there is no reason to suppose that Dragonflies introduced to a pest rich habitat will stay there.
Is the Bigen Speedy Hair Colour does not cover grey perfectly because it works so quickly?
AceringBigen Speedy Hair Colour contains an active agent called "Colour Controller" which prevents the fast acting colour pigments from being oxidized until they penetrate into hair shafts.

How do you colour so well on the computer?
SykoGrafix: Frequently Asked QuestionsWell, just a fair bit of practice, I guess. I've been doing stuff like this for ages now, dating back to when I'd just scribble with a mouse on Microsoft Paint. Unless there was a huge demand, I probably won't be doing any kind of tutorial here on the page. There's lots of other places out there that already have good information on that. You can start by checking my links page. However, I will leave this as a piece of advice.
